How to access the Chart object in Javascript DOM?

I am drawing charts using chart.js. I am doing this dynamically and hence not storing the Chart objects in any Javascript variables and directly just rendering the charts at the run-time. Now I am thinking to build a feature for updating these charts. I know that for updating the charts, we need to use the .update() function. But I am not able to figure out how do I fetch the chart object.

Note: There are many charts on the webpage and new ones are constantly getting added with time. So it is not possible to store the chart objects for my implementation.

To access the chart instance, you can simply use Chart.instances which will return a key-value pair. Values containing the chart instance. You can refer this fiddle as reference.
